研究実績の概要 |
Under this project, I was successful to produce fullerene C60 microcrystals from zero to higher dimensions including newer class of nanocarbon material called mesoporous fullerene crystals with crystalline frameworks. Solvent drying out (upon mild heat-treatment) from the solvated fullerene crystals is expected to play a key role in pore formation. Upon extremely high temperature heat-treatment, the fullerene crystals were converted into a new family of nanoporous carbons having π-electron conjugation within the sp2-carbon robust frameworks. These new nanoporous carbons show excellent electrochemical capacitance and superior sensing properties for aromatic compounds compared to commercial activated carbons. Mesoporous crystalline fullerene C60 exhibited higher surface area (100 to 300 m2/g depending on the system) compared to pristine C60 and displayed enhanced electrochemical supercapacitance. Nevertheless, due to poor conductivity of these crystals, the specific capacitance was found to be less than expected judging from the higher surface area.
